I'm restoring a Soviet clone of C&P sextant (from mid-sixties).
I have an idea of glueing a ~6° (as was suggested by the inventor) prism directly on the horizon mirror. I think of doing it on the outer side of the mirror (on the other side from a clamp-spring), and the width of the prism would be approximatelly 1/3 of the transparent half. Of course the prism should be glued as parallel to the transparen|reflective boundary as technically possible. A friend of mine has an UV-hardening glue for glass - completely transparent when set.
Are there any objections to doing that?
